Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. – Galatians 6:7

You never find a man saying to you, “I don’t profess to be a chaste living man.” You don’t hear another say, “I don’t profess to be anything but a covetous wretch.” No; people are not so fast about telling their faults: and yet you hear people confess the greatest fault to which man can be addicted: they say, “I make no profession”-which means just this-that they do not give God His due. God has made them, and yet they won’t serve Him; Christ hath come into the world to save sinners, and yet they will not regard Him; the gospel is preached; and yet they will not hear it; they have the Bible in their houses, and yet they will not attend to its admonitions; they make no profession of doing so. It will be short work with them at the last great day. There will be no need for the books to be opened, no need for a long deliberation in the verdict. They do not profess to be pardoned; their guilt is written upon their own foreheads, their brazen shamelessness shall be seen by the whole world, as a sentence of destruction written upon their very brows. You cannot expect to win heaven unless your names are entered for the race. If there be no attempts whatever made, even at so much as a profession of religion, then of course you may just sit down and say, “Heaven is not for me; I have no part nor lot in the inheritance of Israel, I cannot say that my Redeemer liveth; and I may rest quite assured that Tophet is prepared of old for me. I must feel its pains and know its miseries; for there are but two places to dwell in hereafter, and if I am not found on the right hand of the Judge, there is but one alternative-namely, to be cast away for ever into the blackness of darkness.”~ C.H. Spurgeon
